DESCRIPTION:
BRIEF SUMMARY
The invention relates to a suspended electric lamp with two conducting wires which serve for power supply and for holding the suspended lamp and further to a lighting system using such a suspended lamp.
Such suspended lamps of the above-described kind are already existing. Up-to-now such suspended lamps were mounted at the ceiling at a fixed point where the electric connector is arranged. Alternatively one can provide several connectors and the suspended lamp may be hung anew, e.g. by means of a plug connection. If the suspended lamp is required in more than one place, several electric connectors must be provided for, which is not very favorable with respect to the optic impression. If there is no plug connection, the lamp must be dismounted every time and has again to be assembled anew via lister connecting means.
In contrast thereto the invention is based on the object of creating an suspended electric lamp which can be arranged to one's liking within a large space without disconnecting it or without assembling work.
For this purpose the suspended electric lamp according to this invention is characterized in that the conducting wires at their ends are loosely connectable to two tensioned lead-in wires fed with low voltage.
In the suspended lamp according to this invention it is advantageous that it can be arranged to one's liking within the range of the tensioned lead-in wires without the necessity of changing connections or assembling works. Moreover, the simple way of connection between the conducting wires and the lead-in wires allows an esthetically attractive solution, as there is no need of connecting means between the conducting wires and the lead-in wires.
Advantageous embodiments of the connection between the conductive wires and the lead-in wires are provided in some examples of the present invention. In these examples there are no particular respective connecting means so that handling is simple.
In a further advantageous embodiment of the invention, a lighting system is created comprising a low-voltage source, at least two tensioned lead-in wires and at least one of the suspended lamps. The lead-in wires may be fixed in a pattern, e.g. several lead-in wires one beside another or in form of a grid. Thereby the region in which the suspended lamps can be arranged without difficulty is increased.
Now embodiments of the invention are explained with the aid of the enclosed drawings.
In the drawings:
FIG. 1 shows a first embodiment of a suspended lamp with rigid conducting wires;
FIG. 2 shows a second embodiment of a suspended lamp with rigid conducting wires;
FIG. 3 shows an embodiment of a suspended lamp with flexible conducting wires;
FIG. 4 shows a further embodiment of a suspended lamp with flexible conductive wires;
FIG. 5 shows an example of a lighting system with three lead-in wires and several suspended lamps of the kind shown in FIGS. 1-4.
In FIG. 1 two lead-in wires 2, 4 are shown which for example are tensioned in a room from one wall to the other and are anchored in holding means 6, 8. The two lead-in wires 2, 4 are kept at a voltage of 0 V or 12 V, respectively, by a low-voltage source 10. A connecting line 12 between the low-voltage source and the holding means 8 is shown in FIG. 1, it can, however,--as usual--be concealed. The suspended lamp as shown in FIG. 1 comprises two rigid conducting wires 14, 16 and a spherical lamp 18. The two conducting wires 14, 16 end in a socket in the interior of the lamp 18 and thereby form a continuous suspension structure for the lamp 18, when the conducting wires 14, 16 are placed on the lead-in wires 2, 4 as is shown in FIG. 1.
FIG. 2 shows the lead-in wires 2, 4 and the holding means 6, 8 whereas the low-voltage supply has been dropped for the sake of simplicity. The suspended lamp comprises two conducting wires 20, 22 which have hooks 24, 26 at their outer ends, with the aid of which hooks the conducting wires are hung into the lead-in wires 2, 4. From the hooks 24, 26 conducting wires 20, 22 run in an arc downwards to a lamp socket 28 in which t
